Quicktime video in Firefox on Ubuntu

Quicktime doesn't seem to work by default in Firefox on Ubuntu.

To get it working, you'll need to check/install plugins which Firefox uses to play video.

First, remove any other firefox plugins related to video; on my system these included:

sudo apt-get remove mozilla-mplayer
sudo apt-get remove mozilla-plugin-vlc

(I had previously installed these in attempts to get Quicktime working.)

Next install an additional plugin for gstreamer:

sudo apt-get install gstreamer0.10-gl

Now point your browser to some quicktime content (http://www.apple.com/trailers/) and enjoy.

Note: I was previously using the mozilla-mplayer package with some success, though Firefox would periodically crash for some unknown reason when viewing Quicktime content .
